人类离不开动物性食品,但很多肉类、水产品等食物携带有寄生虫病原体.食源性寄生虫是引起重要食源性寄生虫病的病原,主要通过人们进食生鲜或未经彻底加热的含有寄生虫虫卵、包囊或幼虫的食品而感染.与细菌和病毒性食源性病原相比,它们长期以来被人们所忽视.近年来,随着生活水平的提高,食品供应全球化进程的加快,人们饮食来源和饮食习惯呈现多样化,尤其对野味及生食的口感追求,促使食源性寄生虫病成为新的"富贵病",我国城镇居民特别是沿海经济发达地区的感染人数呈上升趋势.食源性寄生虫造成的食品安全问题日益突出,不断呈现流行新特点,成为威胁人类健康的重要因素之一,是一个不容忽视的公共卫生问题.综述了重要食源性寄生虫种类(肉源性寄生虫、鱼源性寄生虫、螺源性寄生虫、淡水甲壳动物源性寄生虫、两栖爬行动物源性寄生虫、植物源性寄生虫、水源性寄生虫)、流行新特点及发展趋势,分析了食源性寄生虫病的防控策略和发展方向,以期提升人们对食源性寄生虫的认识,为保障公共卫生和食品安全提供参考.
